• #7276 33c7c72 Thanks @darshanr0107! - fix: respect markdownAutoWrap: false to prevent text auto-wrapping in flowchart markdown labels with htmlLabels enabled.

  Markdown labels with markdownAutoWrap: false, htmlLabels: false set doesn't work
  correctly.

• #7416 3c069b5 Thanks @Crafter-Y! - fix: architecture diagram lines should now have the correct length

• #6995 9745f32 Thanks @darshanr0107! - fix: Support the htmlLabels Mermaid config value whenever possible

  Swapped SVG arc sweep-flag values in the BT (bottom-to-top) orientation branches of drawArrow() so curves bend in the correct direction. Affects both rerouting and non-rerouting code paths for merge and non-merge arrows.

  Resolves #6593

• #7430 a4bb0b5 Thanks @knsv! - fix: allow colons in stateDiagram-v2 transition and state description text

• #7275 7eed6a1 Thanks @darshanr0107! - fix: change createLabel to call createText

  This adds support for KaTeX and FontAwesome icons loaded via iconpacks in some
  older labels. There are some small changes in formatting due to standardizing this code.

• #7265 2000680 Thanks @omkarht! - fix: prevent unintended opacity on SVG aws icons containing rect elements

• #7139 b7c66a2 Thanks @omkarht! - chore: restore original hexagon and roundedRect implementations

• #7425 f16bfbb Thanks @knsv! - fix: use rounded right-angle edges for ELK layout

  ELK layout edges now default to rounded curve (right-angle segments with rounded corners) instead of inheriting the global basis default. This fixes ELK edges that were curving instead of routing at right angles (#7213). Non-ELK layouts are unaffected and keep their existing basis default.

• #7296 aac86f7 Thanks @darshanr0107! - fix: Ensure correct edge label rendering for ER and requirement diagrams when flowchart htmlLabels are false

• #7019 ace0367 Thanks @darshanr0107! - fix: Mindmap breaking in ELK layout

@mermaid-js/parser@1.0.0

Major Changes

• #7377 7243340 Thanks @aloisklink! - chore: upgrade to Langium v4

  Upgrade @mermaid-js/parser to use Langium v4,
  see https://github.com/eclipse-langium/langium/releases/tag/v4.0.0
  for more details.

  The major breaking changes that impact consumers of this package are:

  • Due to various type-related changes, langium now requires version >= 5.8.0
    of TypeScript.
  • The generated type names from ast.ts have been moved from <typeName> to
    <typeName>.$type
    (langium#1942).

  This also removes a transitive dependency on lodash versions that are vulnerable
  to CVE-2025-13465, although
  chevrotain doesn't use the affected functions,
  so this is only to silence security scanners.
